In 2021 when Microsoft announced Windows 11, one of the biggest changes the new operating-system included did not concern the new features however the computers where it had been supposed to be installed.

Windows 11 was therefore offered with upgraded system requirements, essentially abandoning lots of devices which, at least initially, seemed perfectly able to running the OS.

Leaving aside the controversy produced by this approach, Windows 11 was therefore blocked on lots of computers.

The upgrade mysteriously turned up on unsupported devices this past year, despite Microsoft clearly proclaiming that computers not meeting the machine requirements would stick to Windows 10 until 2025 when the support comes to an end.

And earlier this week, everything happened again, with Microsoft once more providing the upgrade to Windows 11 to unsupported devices because of what Microsoft describes being an accident.

Inside a post around the Windows Health Dashboard, Microsoft says that the computers offered the upgrade weren't allowed to complete installing Windows 11 anyway. The issue has already been resolved, the company claims.

"Some hardware ineligible Windows 10 and Windows 11, version 21H2 devices were offered an inaccurate upgrade to Windows 11. These ineligible devices didn't meet the minimum requirements to operate Windows 11. Devices that experienced this issue were not able to to accomplish the upgrade installation process. This issue was detected on February 23, 2023, and resolved on the same day," Microsoft explains.

The organization still recommends users to stay with Windows 10 if their devices don't meet the system requirements to run Windows 11. Windows 10 will receive updates until 2025, at which point this OS version is going to be retired. Upgrading the hardware will become the only option, as otherwise, no further security updates could be available.
